If you’re reading this article beside a window, or perhaps enjoying it outside on a lovely summer day, try to find the sun in the sky. He calculated the distance and size of the moon during an eclipse. Meanwhile, in the heart of the star, mass is converted into energy. Our solar system would lose its only star. Put our Sun next to a supergiant star, and you wouldn’t even be able to spot it. That's about 30 times farther than the distance from Earth to the sun. eval(ez_write_tag([[300,250],'scienceabc_com-leader-2','ezslot_6',180,'0','0']));Numbers on the galactic scale can quickly get out of hand, and size is a difficult concept to grasp for our earthbound minds, but it’s certainly worth trying to grasp. Clouds of dust and gas spewing from one of Triton's powerful cryogeysers are partially obscuring a tiny sun, now but one-thirtieth the size as seen from Earth. When it comes to mass, our star is 330,000 times more massive than Earth. Finally, which is the most telling how big the Sun really is, the Sun's volume is 345,000,000,000,000,000 compared to Earth's volume, which is 260,000,000,000. Largest star ever discovered, compared to our Sun - YouTube New York, This is a size that is almost difficult to imagine. The sun is actually the biggest star that is visible to human eye and as a matter of fact, the biggest start in our entire solar system. The mass of the Sun (the amount of stuff) is 330,000 times that of the Earth. Multiply that by all the seconds in one year, and you get 5.8 trillion miles (9.5 trillion kilometers). Space Chat with Space.com: Tune in Fridays for science, space and more! These elements will collect in the center of the sun. The distance from Earth to the Sun is 93 million miles (149 million kilometers), but the distance to the farthest planet Neptune is nearly 3 … That honor goes to R136a1, which weighs in at about 300 times the mass of the sun but only about 30 solar radii. That could be a problem if you are planning to skirt the edges of the next solar eclipse. Click on a planet or the Sun for details on composition, mass, gravity, and number of moons.

Our sun is a G-Type Main Sequence star, and is classified as a yellow dwarf, currently converting hydrogen into helium through a process of nuclear fusion in its core. Polaris is the nearest star to earths north pole direction. Thus, the real estate on the Sun is about 11,900 times larger than Earth in square miles.
